MUS (Motiva Unreal Scene) has been acquired by Epic Games and rebranded as Datasmith / Unreal Studio

datasmith announcement

At the SIGGRAPH Unreal Engine User Group on July 31, we gave the first public preview of the new workflow toolbox we’re working on, Datasmith, and announced a private beta program. Developed to help artists and designers simplify the process of importing data into Unreal Engine, Datasmith initially supports more than 20 CAD and digital content creation sources, including Autodesk 3ds Max. Other tools will become available as the beta program progresses.
